The 8087 chip provided fast floating point arithmetic for the original IBM PC and became part of the x86 architecture used today. One unusual feature of the 8087 is it contained a multi-level ROM (Read-Only Memory) that stored two bits per transistor, twice as dense as a normal ROM. Instead of storing binary data, each […]

A Weather station project is a project that gives you information about the weather in a particular area and is quite useful for a lot of things like planning of the day, farming and several others. A weather station project is one of those projects where you can have different types of sensors attached to it.

One of the useful side effects of the ubiquitous availability of cellular network data modules is that they can be used to create custom mobile phones. It’s surprising in a way that we don’t see as many of these projects as we’d expect, but by way of redressing that deficiency we’re pleased to see the

Developed in the dark hours of the night, between 2 and 8 o’clock in the morning of August 19th by Marcelo Samsoniuk, the DarkRISC-V stack is an experimental open source implementation of the RISC-V standard targeting the low-cost Xilinx Spartan-6 family of FPGAs. Following a week of debugging, Samsoniuk has released the implementation to GitHub

Just when we think we’ve seen all possible combinations of 3D printing, microcontrollers, and pretty blinkenlights coming together to form DIY clocks, [Mukesh_Sankhla] goes and builds this geometric beauty. It’s kaleidoscopic, it’s mosaic, and it sorta resembles stained glass, but is way cheaper and easier. The crucial part of the print does two jobs — it
The pursuit of audiophile hi-fi is one upon which many superlatives and perhaps a little too much money are lavished. But it’s also a field in which the self-builder can produce their own equipment that is as good or often better than that which can be bought, so it provides plenty of interesting projects along

If you are dealing with solar or battery power, you might want to have one of these little energy meters built by [Open Green Energy] around. The Arduino-based instrument measures DC voltage, current, power, energy, capacity, and temperature. The range is only up to 26 volts and 3.2 amps, but you could extend that with some external

Bowling is great and all, but the unpredictability of that little ball jump in Skee-Ball is so much more exciting. You can play it straight, or spend a bunch of time perfecting the 100-point shot. And unlike bowling, there’s nothing to reset, because gravity gives you the balls back. In one of [gcall1979]’s earlier Skee-Ball
Electronics designers can boost their productivity with free symbols & footprints for Samtec products Samtec is releasing new digital models for over 100,000 of its products on SnapEDA, the industry-leading circuit board design library. Traditionally, designers have spent days creating digital models – such as symbols and footprints – for each component in their designs.
